1. Clip 1 of 10 (0:49)
- tuft testing top side
- 0 to 50 km/h (~30 mph)
2. Clip 2 of 10 (0:34)
- tuft testing top side
-
50 to 80 km/h (~30 to ~50 mph)
3. Clip 3 of 10 (0:39)
- tuft testing passenger side
- 0 to 50 km/h (~30 mph)
4. Clip 4 of 10 (0:34)
- tuft testing driver's side
- 0 to 50 km/h (~30 mph)
- door mirror folded back
5. Clip 5 of 10 (0:37)
- tuft testing effects of added wheel fairing
- 0 to 50 km/h (~30 mph)
- door mirror folded back
6. Clip 6 of 10 (0:33)
- tuft testing added wheel fairing
-
with front fender skirt
- 0 to 50 km/h
- door mirror folded back
7. Clip 7 of 10 (0:40)
- tuft testing bottom
- main undertray not installed
- 0 to 50 km/h (30 mph)
8. Clip 8 of 10 (0:44)
- tuft testing bottom,
aft view
- main undertray not installed
- 0 - 50 km/h (30 mph)
9. Clip 9 of 10 (0:44)
- tuft testing bottom
- main undertray installed
- 0 to 50 km/h (30 mph)
10. Clip 10 of 10 (0:45)

The difference between clips 6 and 4/5 after adding the front wheel skirt was clear on the tufts on the back of the car.
(OT: still, I didn't see any coast-down or fuel economy improvement when I tested mine. Frontal area increase + poor lower aft design is my guess why mine didn't work.)
